ya know how distance can't be applied to x and y cords, here ya go!!! Basically, press space bar once for your first point, then press space bar again for the second point, it automatically draws a line between the 2 and if ya press it again, it shows the distance between the 2 points. Really usefull for many things actually, I myself used it for the swing in one of my games https://scratch.mit.edu/projects/951383246
